Glad to know you worship the god Science.
What being intrudes the womb to implant this "nervous system" in the fertilized egg?

Science is a methodology used to observe and describe the physical world. Yes, I am a scientist. It is a natural career choice for someone as rooted in logic and curiosity as I have been my whole life.
You should be glad for science and the scientific method. Without a scientific description of human embryonic development, the pro-life movement would have died out decades ago, except for a few hold-outs who would be widely regarded as kooks. But since we do have science, the pro-life movement is actually able to point out physical characteristics of the embryo and explain that those characteristics make it a human being worth protecting. Characteristics like the fact that when the nervous system starts to form at three weeks the embryo becomes aware of its world and able to feel. The nervous system consists of the brain and the network of nerves that carry signals between the brain and the rest of the body. Without a nervous system, life can exist, but it is unaware, like plants.
